摘要：Techniques are described to furnish an IR suppression filter that is formed on a
glass substrate to a light sensor. In one or more implementations, a light sensor includesa substrate having a surface. One or more photodetectors are formed in the substrateand configured to detect light and provide a signal in response thereto. An IR
suppression filter configured to block infrared light from reaching the surface is formedon a glass substrate. The light sensor also includes a plurality of color pass filtersdisposed over the surface. The color pass filters are configured to filter visible light topass light in a limited spectrum of wavelengths to the one or more photodetectors. Abuffer layer is disposed over the surface and configured to encapsulate the plurality ofcolor pass filters and adhesion layer. The light sensor further includes through-siliconvias to provide electrical interconnections between different conductive layers.
